AUTOMATIC EGG=B|LER.

i SPECIFICATION forming part of Letters Patent No. 681,184, dated August 2*?, 191.

` Application filed April 8, 1901 l `To cr/ZZ whom, it may concern,.- Be it known that LCHARLES HBLANCHARD, `a `citizen of the United States of America, and

a resident of Batavia, in the county of Clermont and State of Ohio, have invented cerfp tain new and useful Improvements in Automatic Egg-Boilers, of which the following is aspecicatiOn.' The object of my invention is to provide an legg-boiler for automatically lifting a vessel i .holding eggs out of theliquidwhich has boiled them, after a predetermined period, which is accurate in its operation, simple in its con- C g struction, always ready for use, the setting of which requires a minimum amount of time, land which may easily be changed for varying the time of immersion of the eggs. This ob- A ject is attained by the means described in the annexed specification and illustrated in the accompanying drawings, in which*- Figure 1 is a perspective view of two of my egg-boilers attached to a side of a vessel, u one of the boilers being shown set and the other after it has raised the vessel containing ,the eggs. Fig. 2 is a central transverse seci `tional view through one of the boilers, show- N `ing it in its raised position. Fig. 3 is a simii lar view of the same, showing it set. Fig. t i is a view in rear elevationof the vertical col- :umn which guides the weight and in section i d of the timepiece. Fig. 5 is a detail View, upon i. an enlarged scale, of the latch which engages `the timepiece and of the arm and the mov- 1` able weight the changing of which upon the ,arm varies the length of the period of im- 3 mersion. Fig. 6 is a detail view, in side elevation, showing the operation of setting the l timepiece.

. Referring to the parts, vertical column A, within which slides an overbalancing-weight xa, may be secured to the side of any suitable vessel B, within which the boiling liquid is held. Column A has at its upper edge two up-` wardly and outwardly projecting lugs, which support a shaft upon which is journaled a pulley d', over which passes a cord or chain d a2 for connecting weight a and receptacle C, `within which the eggs to be boiled are placed. l Column A has upon its rear side two lugs aija, in which is j ournaled a shaft or fulcrum d, upon one end of which is secured timepiece D. Timepiece D is in the shape of an Serial No. 54,824. (No model.)

hour-glass-'fthat is, consists of two equal closed vessels, connected by a contracted neck, through which sand or other substance will iiow at a fixed rate from one to the other of said vessels. Upon shaft CZ, between lugs c3 0.4, is a trigger d', opposite which is a vertical slot a in the rear wall of the column,- through which the trigger may project underneath Weight a to support it in its upper p0- sition, as shown in Fig. 3.

At the upper edgeof column A, upon the front face, are two forwardly-projecting lugs a6 a7, between which is journaled a shaft e, the outer end of which is square and fits a square hole in rearwardly-projecting arm e', upon which is a weight e2. Upon shaft e, adjacent to arm e', is journaled a latch c3, which has a detent e4 atits outer end to engage the upper edge of timepiece D. Latch c3 has a rounded enlarged hole to pass shaft c, so as to turn thereon, and a pin c5, which 'abuts against the lower edge of arm e', to keep latch e3 from hanging down vertically when it is not engaging timepiece D. Shaft e has an inwardly-projecting detent e, which engages the upper edge of column A to hold arm e in position shown in Fig. 6 when not restingon top of timepiece D.

In use, the sand being collected in one end of timepiece D, receptacle C, containing the eggs, is lowered into the water, thereby carrying weight a, up, as shown in Fig. 3, and timepiece is rotated to bring the end containing the sand up to engage latch es, thereby `bringing trigger d beneath weight a. Latch e3 automatically engages the upper edge of vessel D when it in its rotation raises arm e.- The sand immediately begins running into the lower end of vessel D, and when'sufcient sand has run into the lower end its weight throws vessel D to a vertical position, thereby releasing weight a, which falls `and carries egg-receptacle up out of the water, as shown in Fig. 2. As is seen, when weight e2 is slipped nearer shaft e it requires less sand in the bottom of vessel D to bring it to a vertical position and the time of immersion is thereby shortened. The points upon arm e at which weight e2 must be placed to insure certain periods of immersion are marked upon the arm, so that the only change to be made to have hard, medium, or soft boiled eggs is to IDO shift weight e2 to the point so marked on arm e'.

It is of course obvious that many mere mechanical changes might be made in the means shown without departing from the spirit or scope of my inventions-Las, for instance, itv

would be but an inferior modification of my f end tothe weight and at the .other 'to -the re- 1 ceptacle, :ashaft journ-al'ed near the path of i the Weight and having a trigger ,to retain the Weight against .the action of gravity, a tim-epiece upon the shaft consisting `of .closed vessels .connected Aby a contracted neck and centaining a substance to flew from one lto the p other of said vessels at a fixed rate, and af latch to hold the timepiece at an angle'to the 1 verticaland @the trigger in engagement with the weight, substantially as shown and ,de g scribed.

2. In aniegg-boilerthecombination of a vertical hollowicolumn, a'weight te slide therein, a pulley journaled at the upper end of the column, `a .shaft journaled upon .the side of the column yand lhaving a trigger to project 1 underneath .the weight to hold it raised, al

timepiece consisting of two closed vessels connected by a contracted neck secured to the lshaft in a position such lthat when vthe x trigger is in the path of ,the weight the .timepiece is at an angle to the vertical, a substance wit-hin the timepiece which will iiow from one to the other of the vessels at a uni-y at the other to the egg-receptacle, substanl tial-1y as shown and described.

3. In an egg-boiler the combination of a hol= low column, a weight to be carried downward in thecolu-mn by theaction of gravity, a pnl; ley journaled above the Weight, an egg-receptacle, a cord passing over the. pulley and Connected at one .end to the' Weight and vat the other to the pulley, a shaft journaled `upon .the side of the column, a 'trigger upon the yshaft to project beneath .the weight, a timepiece .consisting of two closed vessels connected by a contracted Vneck and contain= ing a substance which will flowfrom one of said vessels to the `.other-,at a uniform rate secured upon the `sha-tt in a position `szucrh that when' ,the :timepiece is at :an yangle to the vertical the trigger projects beneath .the

weight, a latch to hold the timepiece at the angle vto the Vertical while the :upper-end is the heavier, an .arm `to rest upon the vupper end `of the timepiece While it is in said position and a weight to be fixed ,at vario-us points upon said arm, substantially as shown and described.
